P, C and T for Truly Neutral Particles

Abstract

We present a realization of a quantum field theory, envisaged many years ago by Gelfand, Tsetlin, Sokolik and Bilenky. Considering the special case of the (1/2,0)+(0,1/2) field and developing the Majorana construct for neutrino we show that a fermion and its antifermion can have the same properties with respect to the intrinsic parity (P-) operation. The transformation laws for C- and T- operations have also been given. The construct can be applied to explanation of the present situation in neutrino physics. The case of the (1,0)+ (0,1) field is also considered.
